VOC Recovery Solution for PVC Glove Production Lines

In PVC glove manufacturing, solvents like D70 and D80, along with plasticizers such as DOP, are essential for achieving the flexibility and durability required in medical, industrial, and household gloves. The dipping process relies on these materials to ensure smooth production and consistent product quality. However, the use of solvents also leads to the release of VOCs, which pose environmental and workplace safety concerns if not properly controlled. While PVC gloves represent a major application of high-plasticizer formulations, similar materials are also used in artificial leather, inflatable products, hoses, cable insulation, and films. In contrast, lower-plasticizer or solvent-based formulations are found in adhesives, protective coatings, shoe soles, foam products, sheets, and other rigid or semi-rigid PVC applications.

Sustainable Solutions for VOC Management

Efficient VOC capture is vital to mitigate these risks. Kleanland’s VOC Capture Solution employs advanced technologies like adsorption, condensation, or catalytic processes to recover and purify VOC emissions from production lines, converting them into reusable solvents. This approach not only reduces harmful emissions and environmental pollution but also enables factories to lower raw material costs, enhance economic efficiency, and align with sustainable development goals. By bridging industrial productivity with ecological responsibility, such systems demonstrate how technological innovation can address both economic and environmental challenges in modern manufacturing.

Successful Cases Through out PVC Glove Manufacturing Industries

The Production Process of PVC Glove Production

The production of PVC gloves involves a baking process where raw materials and additives are blended into an emulsion in precise proportions. This emulsion is then pumped into dipping tanks on the production line.

1. Dipping Process:

• Hand-shaped moulds (formers) on a conveyor system automatically dip into the emulsion.
• The moulds rotate as they dip, ensuring that the emulsion coats their surfaces evenly.

2. Curing in the Oven:

• The coated moulds move into an oven set at 230–250°C, where the emulsion cures and forms into gloves. This step is crucial for shaping and solidifying the gloves.

3. Cooling and Lip Rolling:

• After curing, the moulds exit the oven and are naturally cooled.
• A lip rolling process is performed to create smooth and reinforced glove openings for easier donning.

4. Glove Removal:

• The gloves are removed from the moulds either manually or by an automated system.

5. Inspection and Packaging:

• The gloves are inspected to ensure they meet quality standards, checking for defects like tears or uneven surfaces.
• Approved gloves are packaged and stored as finished products, ready for distribution.

This process ensures that PVC gloves are produced with consistent quality, durability, and comfort, meeting the needs of medical, industrial, and general-use applications.

VOC Waste Pollution from Medical PVC Glove Production

The Raw Materials Used in PVC glove production:

PVC Resin: The main component of the gloves is polyvinyl chloride resin.

Plasticizers: Additives like phthalates or alternative non-phthalate plasticizers are mixed to make the material flexible.

Stabilizers and Fillers: Heat stabilizers and fillers are included to enhance durability and thermal resistance.

Color Pigments (optional): For colored gloves, pigments are added during this stage.

The Gas Purification and VOC Recollection from PVC Glove Production Line

Based on the characteristics of the exhaust gas from PVC glove production process, this Kleanland offers gas purification and VOC recollection solution. The process flow of Kleanland solution will use a smoke collection system (fan, ducts) → cooling system → primary purification system (electrostatic adsorption) → extraction and discharge system (end fan, ducts, chimney). A process flow diagram is shown below.



Kleanland Solution for Air Cleaning and VOC Recycling Collection

Given the specific nature of the exhaust gases, this solution is designed with the following key components in the treatment process: 
Smoke Collection and Cooling: The exhaust gases produced during the glove manufacturing process, which contain hot steam and oil fumes, are first collected by a smoke collection system. These gases are then directed through ducts to a cooling unit. In the cooling unit, circulating water reduces the temperature of the exhaust gases to below 30°C. This cooling causes the pollutants to condense into larger particles, which are easier to remove.
Electrostatic Purification: The cooled exhaust gases are then directed into an electrostatic oil smoke removal system. High-voltage electrostatics charge the oil smoke particles, causing them to stick to the anode plates of the device. Once collected, these charged particles flow down to the bottom of the system and are discharged through a pressurized pipe designed to safely remove the contaminants.
Exhaust Gas Discharge: The purified air is then transported by an induced draft fan through ducts and is finally released into the atmosphere through a chimney, ensuring that only clean air is discharged.
Fire Safety Features: The entire system is equipped with an automatic fire safety mechanism. If the system detects a fire hazard or a temperature anomaly, the fire protection system is triggered instantly. The process includes shutting off power to the electrostatic equipment, quickly closing fire dampers at the equipment’s front and back to contain the fire, and opening an electric valve to release firefighting water into the equipment. The system also activates both visual and audible alarms to alert personnel of the emergency.
This integrated process ensures the efficient purification of exhaust gases while prioritizing safety and compliance with environmental regulations.

Kleanland Rotary Carbon Adsorption

1. Adsorption Process (VOC Capture)

Adsorption is a surface phenomenon where gas-phase VOCs adhere to the surface of a solid (activated carbon) due to Van der Waals forces and capillary condensation in micropores.
Activated carbon has a high surface area and porous structure, allowing it to effectively trap VOC molecules.
The efficiency of adsorption depends on temperature, pressure, VOC concentration, and the nature of the VOCs (e.g., polarity, molecular weight).

2. Desorption Process (VOC Recovery & Carbon Regeneration)

Desorption is the reverse process of adsorption, where VOCs are removed from the activated carbon using heat, steam, vacuum, or inert gases.
This process allows the carbon to be reused and the VOCs to be condensed and recovered for reuse.
